I want to set up a room with 4 Direct TV receivers and TVs to watch football on Sundays. I have a few questions: How do all the remotes work? If I want to change the DirecTV channel on one receiver, will the remote change all the receivers at the same time? Do I need different brands of receivers to get around this? Same question with the TVs - if I have all Sony TVs and try to change the channel will they all move at once? As far as hooking up the DTV receivers, I assume they each have to be hard wired from the dish. I've seen 4 way splitters - is there a limit of splits I can do from a dual-LNB dish? Any suggestions/input would be great. Thanks.
